Objective: The purpose of this study was to investigate the effects of the Power Card strategy on the receptive vocabulary and expressive vocabulary in children with autism spectrum disorders. Method: Three children with autism spectrum disorder were selected for this study and the power card strategy language intervention was applied, using a multiple baseline design across individuals. The target vocabulary was selected by examining the individual preferred characters. Power cards were constructed, and intervention was applied to improve the receptive vocabulary and expressive vocabulary through the baseline stage, intervention, and maintenance. Result: The application of the power card strategy showed that the acquisition rate of receptive vocabulary in children with autism spectrum disorder was increased, and expressive vocabulary acquisition rate was also improved. Conclusion: During the intervention period using the power card strategy, the children's target receptive vocabulary and expressive vocabulary acquisition rates improved, and the acquisition rate was maintained, even after the intervention. This suggests that the power card strategy is effective in improving the vocabulary of autistic children with disabilities, of school age.

Objectives: The purpose of this study was to assess the effects of Korean medicine for non-alcoholic fatty liver disease (NAFLD). We analyzed the result of randomized controlled trials (RCTs) that applied Korean medicine to NAFLD patients through meta analysis and systematic review. Methods: The key question was to the effects of Korean medicine for NAFLD patients according to the PICO-SD (participants, intervention, comparison, outcome, study design) and we included only RCTs. We searched 10 databases including NDSL, KMBASE, KISS, KISTI, KoreaMed, Koreantk, OASIS, Cochrane, Pubmed, EMBASE without a language restriction. We assessed risk of bias by Cochrane group's Risk of Bias tool. Results: The finally selected 12 RCTs were analyzed. Total number of participants was 1189 (male 719, female 470) as 684 and 505 in the oriental medicine group (i.e. herbal drugs, acupuncture, acupoint embedding therapy) and control group (conventional drugs, placebo), respectively. The meta analysis results of examining 7 RCTs comparing the therapeutic efficacy of herbal medicine with that of Western medicine showed statistically significant (p<0.05) differences in the efficacy evaluation, liver function test results, blood lipids, and TNF-${\alpha}$. Furthermore, the meta analysis results of investigating 3 RCTs comparing the therapeutic efficacy of herbal medicine with that of a placebo showed statistically significant (p<0.05) differences in the liver function test results, blood lipids, and waist circumference. Conclusions: The research showed that Korean medicine for NAFLD can be effective treatment. But more studies are required to enhance the level of evidence and we should report on safety.

Objective: The objective of this study was to compare the quality of life (QOL) of patients with end-stage renal disease (ESRD) between patients receiving hemodialysis (HD) and patients receiving continuous ambulatory peritoneal dialysis (CAPD) and to compare personal characteristic factors relating to the quality of life in patients with ESRD. Method: This study used a descriptive research design. The sample was recruited using purposive sampling that included 76 ESRD patients receiving either HD or CAPD at a dialysis clinic in Phraphutthabat Hospital, Saraburi Province, Thailand. Data was collected using the Quality of Life Questionnaire for Chronic Kidney Disease ($KDQOL-SF^{TM}$) version 1.3. Independent t-test and ANOVA procedures were used to analyze study data. Results: The results revealed that the HD patients had a moderate level of QOL. The highest scoring dimension of QOL was the encouragement of staff at the dialysis unit and patient satisfaction with the treatment (${\bar{X}}=100$, SD=.00), followed by social support (${\bar{X}}=89.29$, SD =16.88) and cognitive function (${\bar{X}}=88.57$, SD=11.82). On the other hand, the lowest scoring QOL dimension was physical problems (${\bar{X}}=50$, SD=51.89), and pain (${\bar{X}}=50$, SD=39.03), followed by work status (${\bar{X}}=53.57$, SD=45.84) and burden from kidney disease (${\bar{X}}=58.48$, SD=31.07). The CAPD patients also had a moderate QOL. The highest scoring QOL dimension was the encouragement of staff in the renal unit and patient satisfaction with the treatment (${\bar{X}}=100$, SD=.00), followed by social support (${\bar{X}}=95.61$, SD=14.20) and cognitive function (${\bar{X}}=88.83$, SD=13.52). The worst scoring QOL dimensions were work status (${\bar{X}}=44.44$, SD=42.72), general health (${\bar{X}}=53.61$, SD=39.05), and pain (${\bar{X}}=62.70$, SD=41.14). The difference overall and in each dimension of QOL in ESRD patients who were treated with HD and CAPD was not statistically significantly different. The QOL was not significantly different among patients with different personal characteristics except for income and duration of treatment; in those cases, the difference in QOL was statistically significant (p=.05). Conclusion: The overall QOL and life expectancy of patients with ESRD treated with HD and CAPD are not affected by gender, age, marital status, education, occupation, or type of health coverage. QOL was not significantly different, except for patients with different incomes and duration of renal replacement therapy, whose QOL was significantly different. The QOL of patients receiving dialysis should be studied to develop a QOL program for patients with chronic kidney disease who receive dialysis.

The purpose of this study was to compare the immediate effect of EMS (electrical muscle stimulation) on rectus femoris thickness during resisted knee extension exercise in healthy adults. This experiment was conducted on 20 healthy adults as pretest-posttest nonequivalent one group design. The subject's 1RM of both knee extension was measured indirectly using an elastic band, and the knee extension resistance exercise using an elastic band was applied to high intensity (80% of 1RM) on the right leg and low intensity (50% of 1RM with EMS) on the left leg, which were applied with 5 sets. Muscle measurements were performed on the rectus femoris (1/2 site, 1/4 site) using ultrasonography before and after exercise. There was a statistically significant difference on the thickness of the rectus femoris in low intensity exercise of the elastic band applied with EMS between pre-test and post-test (p<.05). The results of this study showed that elastic band low intensity exercise combined with EMS had an immediate effective in increasing the thickness of rectus femoris. Based on this result, it is also necessary to verify the effectiveness of intervention methods incorporating low-intensity resistance exercises applying EMS to elderly who cannot exercise high-intensity resistance training in the future, and to develop exercise programs for various body parts.

The purpose of this study was to confirm the effect of mindfulness education on perceived stress, mindfulness, psychological well-being, and brain waves. The study used a repeated-measures design to examine 42 female university students currently enrolled in mindfulness courses. Subjects participated in the mindfulness course once a week for eight weeks, 50 minutes per session. The main outcome variables, such as perceived stress, mindfulness, and psychological well-being, were measured with a structured questionnaire and brain waves were measured with an electroencephalograph. The same variables were then measured after the completion of the eight-week course. The results demonstrate that perceived stress significantly decreased from 1.85±0.39 to 1.66±0.39 points (t=3.44, p=.001), while, on the other hand, mindfulness increased from 3.10±0.26 points to 3.19±0.32 points (t =-2.78, p=.008). There was also a significant difference in the level of autonomy, a subcategory of psychological well-being (t=-2.70, p=.010). In addition, EEG indicated significant changes in the frequencies of Theta channel 19 and Rapid Alpha channels 7 and 10. These results suggest that further studies are needed to elucidate the effects of mindfulness education through the modification of mindfulness course plans, diversification of teaching methods, and improvement in the educational environment.

The non-face-to-face environment accelerated by COVID-19 has speeded up the dissemination of digital virtual ecosystems and metaverse. In order for the metaverse to be sustainable, digital twins that are compatible with the real world are key, and critical technology for that is AR (Augmented Reality). In this study, we examined research trends about AR, and will propose the directions for future AR research. We conducted LDA based topic modeling on 11,049 abstracts of published domestic and foreign AR related papers from 2009 to Mar 2022, and then looked into AR that was comprehensive research trends, comparison of domestic and foreign research trends, and research trends before and after the popularity of metaverse concepts. As a result, the topics of AR related research were deduced from 11 topics such as device, network communication, surgery, digital twin, education, serious game, camera/vision, color application, therapy, location accuracy, and interface design. After popularity of metaverse, 6 topics were deduced such as camera/vision, training, digital twin, surgical/surgical, interaction performance, and network communication. We will expect, through this study, to encourage active research on metaverse AR with convergent characteristics in multidisciplinary fields and contribute to giving useful implications to practitioners.

Objective : This study was intended to systematically consider the sensory integration intervention methods offered in Korea for children with autism spectrum disorder and to provide an evidence base for the application of sensory integration interventions. Methods : The subjects of this study were published studies in a national journal for the last 10 years from January 2011 to December 2020. The databases used for the search were RISS and DBpia. The search terms were 'autism', 'autism spectrum', 'sensory integration', and 'intervention'. A total of 10 studies were used in the analysis, which were analyzed at the qualitative and methodological quality of the research evidence and the results were presented according to the PICO (Patient, Intervention, Comparison, Outcome). Results : In the research analysis, the quality level of the evidence was highest at level IV, followed by level II. The methodological quality of the evidence was the most common for 'Good' research, followed 'Fair'. The study subjects were children with autism spectrum disorder and their parents, and the experimental design had the highest frequency of single-subject studies. Interventions have the highest number of studies confirming adaptive behavior and sensory modulation, and the evaluation tools used to measure interventions have the highest frequency of sensory profiles and Canadian occupational performance measures (COPM). All 10 studies used in the analysis showed positive improvements and statistically significant effects on various outcome values from sensory integration interventions. Conclusion : In the recent clinical environment, sensory integration interventions have been continuously conducted in children with autism spectrum disorder. In future research, it is necessary to conduct research on various sensory integration intervention methods and the high quality of the evidence for the application of sensory integration interventions.

The purpose of this study was to investigate the effects of a tactile-oriented sensory-motor developmental program on the visual attention and stereotypical behavior of an adolescent with intellectual disability. The subject was an adolescent with intellectual disability attending a special school located in B-gun, A-province of South Korea, with whom an A-B-A' design individual target study was conducted between August 27 and December 12, 2018. The intervention consisted of twelve 40-minute sessions, which were provided twice a week. For every session, two types of evaluation were conducted: a test that required staring at objects for visual attention, as well as an observation record for identifying the frequency and duration of stereotypical behavior. The results of this study showed that the tactile-oriented sensory-motor developmental program had positive effects on the duration of the participant's ability to stare at objects and the frequency and duration of stereotypical behavior. As this study confirmed and usefulness of this tactile-oriented sensory-motor developmental program as an intervention for improving the visual attention, and stereotypical behavior of adolescent with intellectual disabilities, the program may be employed to help members of this groups who have problems with sensory processing.
